and employing a liquid that may be of petroleum product type or non-petroleum product
type functioning as a source for the flame in combination with a wick that is soaked
in the liquid.
[0005] US 2 001 377 A describes a candle wick comprising a self-consuming fabric wick, a reinforcing strip
extending therealong externally thereof, and a fine wire, fusible at the temperature
at the base of the flame, openly wrapped about the fabric wick and strip for holding
them together.
[0006] US 3 290 907 A describes an apparatus for burning spirit or similar fuel, comprising a fuel container
containing a fuel absorptive usually porous mass and a wick in contact with the absorptive
mass and adapted to transfer fuel from the absorptive mass to the point of combustion,
in which there is disposed within the fuel container a lower fuel absorptive filling
layer and superposed thereon a filling layer having relatively large pores, and between
the large-pored filling layer and the top wall of the fuel container a second fuel
absorptive layer, the said second fuel absorptive layer communicating through a wick
with the bottom layer of fuel absorptive material.
[0007] The present invention is, therefore, intended to obviate or at least alleviate the
problems encountered in the prior art.
